您好，我有一个研究项目，该项目是在仪表板上显示数据，用户可以根据自己的需要对其进行或多或少的修改。

我试图打开一个模态窗口，但它不起作用，我不知道我的错误来自哪里。 

const body = document.querySelector("body"),
  sidebar = body.querySelector(".sidebar"),
  btn = body.querySelector("#btn");

btn.addEventListener("click", () => {
  sidebar.classList.toggle("active");
})

const modalContainer = document.querySelector(".modal-container");
const modalTriggers = document.querySelector(".modal-trigger");
modalTriggers.forEach(trigger => trigger.addEventListener("click", toggleModal))

function toggleModal() {
  modalContainer.classList.toggle("active")
}

补充一下之前的回答，点击关闭按钮后模态窗口不会关闭。只有点击窗口外部才会关闭。这应该可以解决所有问题：删除覆盖类中的 modal-trigger 类。它应该是 <div class="overlay"> 而不是 <div class="overlay modal-trigger"> ，为了演示，我更改了背景颜色 

const body = document.querySelector("body"),
        sidebar = body.querySelector(".sidebar"),
        btn = body.querySelector("#btn");

        btn.addEventListener("click", () => {
            sidebar.classList.toggle("active");
        })

        const modalContainer = document.querySelector(".modal-container");

        const modalTriggers = document.querySelectorAll(".modal-trigger");

        modalTriggers.forEach(trigger => trigger.addEventListener("click", toggleModal))

        function toggleModal() {
            modalContainer.classList.toggle("active")
        }
body {
            height: 100vh;
            background: purple;
        }

现在应该可以工作了，请记住 querySelector() 仅抓取第一个匹配项，您应该使用 querySelectorAll() 方法，该方法是可迭代的，可抓取所有匹配的元素。 

const body = document.querySelector("body"),
  sidebar = body.querySelector(".sidebar"),
  btn = body.querySelector("#btn");

btn.addEventListener("click", () => {
  sidebar.classList.toggle("active");
})

const modalContainer = document.querySelector(".modal-container");
const modalTriggers = document.querySelectorAll(".modal-trigger");
modalTriggers.forEach(trigger => trigger.addEventListener("click", toggleModal))

function toggleModal() {
  modalContainer.classList.toggle("active")
}
